As it is possible that b the Figure 6 is a.v vertical section through the I action-oi this inclined plane it some of the disk:

or the test ng mechanisms. mayf 'mount on others, near this inclined plane at there is arranged another revolving shaft 29 provided also with a spiral and having on its end two fins 29 which causes to fall into the chanvnel |5 the superfluous disks and those which have mounted on others.

In this manner there is obtained the placing of the disks 22 forming a line in which there is no disk on another and during this -movement there is applied on the line of disks two small belts 2| which maintain the disks 'flrmly against the belt 2 at the part where the belt curves around the cylinder 5 and thus singly and sequentially delivers the disks to the testing mechanisms which separate the defective disks from the good ones.

As is seen in more detail in Figures 3 and 6,

the small, belts 2|- which hold the disks firmly on made up of a channel 25 'pivotally supported at" 21 to a part or the machine (Fig. 6) and the other constituted by a lever or plane 25 movably connected to the shaft 29.

when these two pieces are in the position shown in full lines inFlgure c, the disk 22 on coming away from the belts 2| falls and is conducted to the vertical channel 29 to be submitted to further tests, whilst when these pieces 25,

25 are in the position shown in dotted lines in s Figure 6 the disk falls into the channel 30 which conducts it out of the machine. The guide bars or pieces 25 and 25 are arranged to be selectively actuated-during .the'operation of the machine so as to cause the disks to be either delivered-to the channel 29 or channel 30 by suitable electrical means hereinafter described.

At the point in which the belts 2| leave the disk, there is arranged a mechanism which tests the diameter of the disk to separate the pieces and the disks whose diameter is less than the correct one. This mechanism is made up of toggles or jaws 3| pivoted at 22 to the lever 33 and connected at their, upper ends to a spring 34 I which maintains them normally in a raised and closed position. By means or a graduated stop 95 the separation of these toggles is regulated in such a way that normally their clamping or en gaging ends are'spaced at a distance slightly less thanthe correct'diameter of the disks 22. The-disks 22 are drawn by the belt 2 and the small belts 2| between the lower ends of the tog- .gles 3| and if the diameter of thedisk 22 is cor-,-

rect, as this diameter is greater than the separation oI/the toggles, the advancing disk" draws the toggles downwardly overcoming the action of the spring 34. On the other hand dealing with a piece ora diskoi a diameter less than the correct one, the disk or piece passes freely through the spaced ends of the toggles without drawing them down. When the toggles 3| descend, the lever 32 also descends and thencloses the electric contact 35 connected to an electric. magnet 31 whose armature 39 on being. attracted by the electro-magnet works through the intermediation of the mechanism 39, 49, 4|, operatively connected to the guide members 25, 29, so as to move these members to the position shown in full lines in Figure 6. The armature 29 off the electro-' magnet is combined through a connecting rod 42 witharetardingmechanism whichcauses thesepiecesfl, 251: remaininthisposition during the time necessary for the disk 2; to come loose from the toggles and the small belts 2| and to fall in the channel 29.

K From the channel 29 the disk passes to another testing mechanism in which it is tested to determine its permeability by means of compressed air or vacuum to see if the disk closes hermetically.

This unitary mechanism includes a, wheel or by means of a duct 48 with a small air pump consisting of a membrane 49 which injects through this duct 48 compressed air to test the permeability of closing air tight qualities of the disk.

The movement of the pistons 41 is carried out by means of the levers 59 dijven in their turn by the fixed eccentric in such a way that the same movement of the shaft 55 with the wheels 44, 45, causes the plunger 4 to be reciprocated so as to be applied on the disk 22 and separated from it at predetermined points during the rotation of the wheel 4!.

In a similar way the membranes or .alr pumps 49 are driven by the levers 52 and springs 53. These springs 52 tend to always compress the air by means of the membranes 49 whilst the free end of the levers 52 is driven by means of another fixed eccentric 54 which at the convenient moment leaves them free in order that they may be driven by the springs 53.

The working of this mechanism is as i'ollowsz The disk 22 is introduced in the pocket or slot 45 when this is in the top position, that is to say' immediately below the channel 29 and shortly after continuing the rotation of the wheels 44, 46

brane 49 and the lever 52 hardlyvaries but if' the disk loses, asthe wheel goes on turning, the membrane 49 moves towards the left of Figure 6 until it takes up the position shown in the lower part of this figure.

. Under the wheel 44 and corresponding to the position in which the piston 41 withdraws from the disk 22 there is a movable channel 51 which can take up the three positions shown in Figure 6 corresponding to three ducts or deposits 58, 59, 90.

This channel 51 is driven .or worked on one hand by the spring 99- which tends to place it alwaysin the position shown in Figure 6 by-full lines and on the other hand is worked by stops 63 which at every movement of the wheel 44 places it in'the position nearer the leit where it is retained by the latch 52 so as to align with the compartment 59. In additionthere is another similar latch 6| which serves as a stop or retention piece for the intermediate position of the channel 51 corresponding to the intermediate deposit x does not let the air escape and consequently the membrane remains in the position towards the right, the extension 56 does not touch either. of

the two latches and consequently the channel 51 remains in its position towards the left and conducts the disk to the deposit 56 corresponding to the gooddisks. If the disk allows a small quantity of air to escape the extension 56 works the latch 62 and then the chanel 57 remains in the intermediate position in front of the deposit 59 to which the disks of inferior or doubtful quality If the disk allows the air to escape completely and the membrane remains in the position shown in the lower part of. Figure 6 then the extension 56 works the latch 6| and the swinging channel 51 takes the position corresponding with the compartment or receptacle 66 to which the defective disks go.

This mechanism may be combined also in such a way that the testing of the disks is not made-by air pressure but by vacuum. This variation is shown in Figure 8. In this case the lever I52 and the eccentric I54 have the necessary arrangement for the spring 53 to work the membrane 49 inthe sense of producing an aspiration or vacuum. The mechanism described tests at the same time .whether thetwo faces of the disks are parallel.

To this end each of the plungers 41 rest solely on the point 64 of the stem 65 in such a way that it may oscillate aroundthe same and be joined to a crown or ring 66 which by means of springs rests against another ring 61 forming part of the stem 65. In combination with this, there is arranged on the shaft 65' a sliding sleeve 66 forming part of an arm 69 whichron arriving at the lower part,

contacts with a spring 10 which forms an inclined elastic plane and pushes the sleeve 68 towards the plunger 41. When the two faces of the disk are parallel one to another, the. plunger l! is conveniently applied on the disk and the ring 66 in the top part of Figure 6, and meets with the piece 16 fixed to the shaft II which by means of.

the connection ofshaft II with arm I2 works the pawls 6| and-62 and places the channel 51 inthe position at the right corresponding to the deposit 66 of the defective disks.

This same mechanism tests the thickness of the disks separating the defective enesfor being lever carries a stem or extension". When the disk being tested is of normal thickness, this stem 13 passes freely through the groove 15 of the piece 16 but if the disk is too thick or too thin the stem .13 engages the piece 16. so as to cause the latter to move therewith, movement actuates' the channel or gate 51 through thelinks 1], l2 and theirassociated parts, so as to move. the channel into alignment with the compartment 60 that receives the defective disk.

, It will be observed that I provide asubst'antially' unitary mechanism which serves to director con-- vey the disk through a predeterminedhourse and ,from a series of independent mechanisms through which the discs' might be separately passed.

It will be seen therefore that this machine submits the disks to different tests regarding diameter, thickness, parallelism of its faces, the presence of pores allowing the air to pass, etc and carries out a -much more exact and careful work than could be done by hand in the usual way.
